The Instrumental Duet Series Worship Suite books feature volumes organized into three 3-song thematic medleys. Each song has an ending, so that they may be presented individually, or as two- or three-song medleys. The piano is an equal musical partner with the instrument in these arrangements. A companion split-channel CD is available with the book/CD packs, and can be useful as a helpful practice aid, providing the instrumentalist or piano player a "virtual practice partner." The instrumentalist may also perform with the piano trax if no accompanist is available. Book 4 for violin and piano contents: Jesus, Our Blessed Redeemer Medley (When Morning Gilds the Sky; Our Great Savior; Praise Him! Praise Him!) * Thinking About Home Medley (Goodby, World, Goodby; Sweet By and By; When We All Get to Heaven) * Praise the Creator! Medley (This Is My Father's World; I Sing the Mighty Power of God; Joyful, Joyful, We Adore Thee).
